BOSSTU-3 Chromatic Tuner Pedal

Q: can this tune a saxophone??

Saxophones absolutely need to be tuned every time you take off the mouth piece or with temperature changes such as going from indoors to outdoors on a cold night (marching band). Tuning is done by shortening or lengthening the distance an the neck of the sax by moving the mouthpiece in or out. This tuner could be used to tune a saxophone if you have a cheap mic that has a 1/4". That said there are less expensive tuners with built in mics that would better suit your purpose. Please note though that no matter what tuner you buy, if it is set to concert pitch (440Hz A / piano tuning) you will want to transpose the notes from Bb (tenor) or Eb (alto) to concert pitch when tuning your saxophone. In other words when you play a C on a tenor saxophone it is a Bb in concert pitch. For alto a C is an Eb in concert pitch. There are some very expensive turners that you can change the tuning from concert pitch to other pitches but they are a waste of money since transposing is not difficult. Make a chart or download one if you struggle at first. Remember that your sax could be sharp on some notes and flat on others so check multiple notes and find the tuning where the most notes are in tune and those that are not are just a little sharp or a little flat.

Q: How does the TU-3 effect a fuzz face if it's placed a couple pedals away after the fuzz ? I assume it has a buffer like most Boss pedals.

It is buffered, but the buffer won't affect anything that comes before it. Since certain fuzzes don't "like" buffers, putting those before the tuner will work fine. Guitar > Fuzz Face > Tuner ( or any buffered pedal) > Amp

Q: Is this product adequte for a 10 string pedal steel guitar ? I was told to get a tuner that shows the frequency and I do not see a # on the display

This won't show the frequency in Hertz, but it will indicate pitch, and the 10 string pedal steel should be in its range. There is a dot on the display to indicate a sharp.
